Cincinnati - Three-time Grand Slam champion Andy Murray was beaten 6-4, 6-4 by Richard Gasquet on Monday on his return to singles competition in Cincinnati following a seven-month hip injury lay-off.
The Scot hadn't played a singles match since a first-round exit at the Australian Open in January and feared his career was over, but right hip resurfacing surgery allowed him to return.
However Frenchman Gasquet was too strong for the 32-year-old, who was seen off in straight sets at the warm-up for the US Open.
